VMware Site Recovery Manager
What is SRM?– A DR workflow automation product
What does SRM do?– Simplifies DR, lowers cost and risk– Integrates VI3 with storage replication– Makes DR protection a property of the virtual machine– Allows a preprogrammed DR response

Vmware Requirements
Installed at BOTH Protected and Recovery Sites*:
– ESX Server 3.0.2, ESX 3.5 or ESXi 3.5
– VirtualCenter 2.5 and Virtual Infrastructure Client
– Site Recovery Manager 1.0
– NetApp Site Recovery Adapter 1.0
– Perl 5.8 (by default Perl is included in the SRM distribution)
* This information is current as of Sept 2008, please check latest documentation for up-to-date support
© 2008 NetApp. All rights reserved.
NetApp Requirements
Installed at BOTH Protected and Recovery Sites*:
– FAS 2000, FAS 3000, or FAS 6000 Series Storage platforms
– DATA ONTAP 7.2.2 or above
– NetApp APIs use simple HTTP by default. To use secure HTTPS, you must set up
SecureAdmin and ensure that ssl/ssh is running.
– Because SOAP/HTTP/SSL is used, you must configure the firewall (if any) between Data ONTAP and Site Recovery Manager to keep the corresponding port open
* This information is current as of Sept 2008, please check latest documentation for up-to-date support
© 2008 NetApp. All rights reserved.
NetApp License Requirements
NetApp licenses required on Protected and Recovery Storage:
– SnapMirror
– iSCSI and/or FCP
– FlexClone(required for creating flex clone volumes for Recovery Test)
© 2008 NetApp. All rights reserved.
Supported Replication Products
The following NetApp data replication products are supported with SRM on NetApp– Volume SnapMirror (async & sync)
– Qtree SnapMirror
The following is not supported– SnapVault
– MetroCluster

© 2008 NetApp. All rights reserved.
Supported Configurations
The following configurations are supported– NetApp FCP protocol– NetApp iSCSI protocol– NetApp FlexVol Volumes
The following configurations are not supported*– NFS protocol– Traditional Volumes
(FlexClone technology is not available with traditional volumes)
* This information is current as of Sept 2008, please check latest documentation for up-to-date support
© 2008 NetApp. All rights reserved.
Configuration Guidelines
FlexVol Volumes should be replicated to only one destination– LUNs having multiple replication destinations cannot be
failed over
NetApp SnapMirror replicates data at the volume or qtree level– Only VMs to be replicated should be contained in
replicated volumes
Guest attached storage – software iSCSI inside Guest, SRM does not recover this
storage
Applications running inside VMs are not application consistent

Failback – Reversing SnapMirror
If Primary storage recovered– SnapMirror “resync” in reverse direction
– Only delta of data transferred
– SnapMirror “update” during failback outage
If Primary storage lost– Snapmirror “initialize” in reverse direction
– All lost data transferred
– SnapMirror “update” during failback outage

Troubleshooting – Common Problems
Any issue with the Configure Array Manager– Verify the IP, username and password provided for the
NetApp array is correct
If Array Manager does not recognize replicated LUNs– Verify SnapMirror relationship exists between the
Protection and Recovery Filer and that the volume replicated contains LUN
During DR test no replicated datastore found– Verify Recovery storage has igroup type of vmware that
contains ESX initiators
– Verify replicated LUNs are not already mapped to igroup, SRM must map them
© 2008 NetApp. All rights reserved.
Common Problems, contd.
General NetApp issues– Verify SnapMirror, FCP, iSCSI and FlexClone products
are licensed
– Verify igroup types are created with ostype vmware
– Verify igroups contain ESX initiators
– Verify FCP, iSCSI, and SnapMirror service is running at Recovery site
Any issue with SRM Test Failover– Check if flexclone is licensed on the Recovery filer or not– Verify that no non-replicated datastores exist on the
recovery filer with the same names as the recovery datastore
– Remember, only FlexVol Volumes support this feature
